The film you should see before dating Zac Efron is...

Think you know everything about Zac Efron? We’ll take that challenge. Presenting five facts about the blue-eyed Neighbors star not yet in your fan file…

1. He’s creative about staying sober.

He’s also great with boats. (Warner Bros.)

“Coachella was going on before the (Neighbors) press tour so we did ‘NoChella,'” he told USA TODAY, reflecting on life after a stint in rehab last year. “We just downloaded all the music on Spotify that was going to be at Coachella. My buddy and I got a jeep, filled it with camping gear and just drove across the country on Route 66, and just blasted music on the speakers.”

2. He watches his favorite shows on tiny screens.

“I watch Game of Thrones on my phone,” he says.

3. His parents have had long text conversations with his ghost hacker.

Which he does not, ahem, call beirut. On set of Neighbors, “Nobody knew how to play beer pong!” he says. Cue Efron resetting party props. “It was really weird because everyone was freaked out about how much I knew,” he says. “More cups!” he’d holler. ” ‘There’s liquor everywhere! Tons of people! More teams! More balls! Balls everywhere! This is how the game is played.’ ”
